Model comparison for the effect of 5-HTR blockade on error rate in the work/delay task (for Fig 5C).

CU and E₀ indicate the remaining cost and the intercept, respectively. k(treat), k(type), e(treat), and e(type) denote the random effects of blocking 5-HT on parameters k and e, respectively. The probability distribution of the random effects were as follows: k_treat and k_type were ~N(0,σ²_treat) and ~N(0,σ²_type), respectively. (k’_treat, e’_treat) and (k’_type, e’_type) were ~biNorm(0, ∑_treat) and ~biNorm(0, ∑_type), respectively. E, error rate; treat, treatment condition (antagonist or control): type, trial type (delay or work). BIC is a relative measure of quality for the models (#1–25). ΔBIC denotes the difference from the minimum BIC.
